Note that because we don't get the module list for WARN_ON, we don't
actually know whether all of these instances are from the iwlwifi
drivers. A few other drivers suffer from the same problem. In one of
these cases, iwlwifi was contained in the stack trace, but in the common
case that isn't happening because packet processing is delayed to a
tasklet.
